Product details
Overview
P6KE27C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 37.5 V maximum clamping voltage at 16.0 A peak pulse current, and 23.1 V stand-off voltage - enabling robust protection of MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6KE27C-E3/73 datasheet, P6KE27C-E3/73 pinout, P6KE27C-E3/73 application, or P6KE27C-E3/73 equivalent, key selection criteria include bi-directional clamping capability, UL 497B recognition, AEC-Q101 qualification (HE3 variant), thermal resistance (RθJL = 20 °C/W), and compatibility with 8.3 ms surge waveforms per JESD 22-B106.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 23.1 V), but triggers into low-impedance conduction when transient voltage exceeds its 25.7–28.4 V breakdown range (tested at 1 mA). Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns) to ESD and lightning-induced surges.
The bi-directional configuration eliminates polarity dependency, making it suitable for AC-coupled lines and differential buses. Clamping performance is validated per IEC 61000-4-5 (surge) and ISO 7637-2 (automotive), with thermal derating defined up to 175 °C junction temperature and 75 °C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - maximum continuous reverse working voltage before leakage exceeds 1 μA; defines safe operating margin below clamping threshold |
| VBR min/max | 25.7 V / 28.4 V at 1 mA - guaranteed breakdown window ensuring predictable turn-on across production lots and temperature |
| VC @ IPPM | 37.5 V at 16.0 A (10/1000 μs) - absolute upper limit of suppressed voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capacity without failure; enables single-device protection against IEC 61000-4-5 Level 4 (4 kV) |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; supports sustained 5.0 W power dissipation at TL = 75 °C with minimal heatsinking |
| TJ max | +175 °C - maximum junction temperature rating; allows operation in under-hood automotive environments and industrial enclosures |
| UL Recognition | QVGQ2 file E136766 - certified per UL 497B for telecom and data line protectors; validates safety compliance for end-equipment listing |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bi-directional symmetry confirmed per datasheet Note: "no marking on bi-directional types".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | Either terminal serves as anode or cathode depending on transient polarity; no DC bias dependency required |
| Lead 1 | Current path input/output | Connects to line under protection; bidirectional conduction enables same layout for AC or DC rails |
| Lead 2 | Current path input/output | Connects to reference (GND or return); symmetric terminals simplify PCB routing and reduce layout risk |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures stable VBR drift <±5 % over lifetime and immunity to humidity-induced parameter shift |
| 600 W peak pulse power (10/1000 μs) | Supports single-device protection against ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Combination Wave (4 kV) |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive under-hood use including temperature cycling, mechanical shock, and board-level reliability testing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; 24 V VWM, 38.9 V VC @ 15.4 A; lower RθJA (50 °C/W vs. 75 °C/W) | Better suited for surface-mount layouts with limited board space; higher mounting density but requires reflow-compatible footprint | Select SMBJ24CA when automated assembly and compact PCB real estate outweigh axial-leaded serviceability needs. |
| 1.5KE27C | Same DO-204AC package; identical VWM/VBR/VC specs but rated for 1500 W PPPM; larger die size increases capacitance (≈150 pF vs. ≈50 pF) | Higher energy handling for rare multi-pulse events; added capacitance may degrade >10 MHz signal integrity | Choose 1.5KE27C only where verified surge profiles exceed 600 W single-event limits and bandwidth constraints permit higher CJ. |
Compared with SMBJ24CA and 1.5KE27C, P6KE27C-E3/73 delivers optimal balance of axial-leaded serviceability, UL/IEC-compliant clamping, and thermal performance in cost-sensitive commercial and automotive applications - without compromising surge margin or requiring layout redesign.

FAQ
What is the breakdown voltage range of the P6KE27C-E3/73?
The P6KE27C-E3/73 has a guaranteed breakdown voltage (VBR) range of 25.7 V to 28.4 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across temperature and production lots, critical for protecting 24 V systems where overvoltage margin must be precisely controlled. The P6KE27C-E3/73 maintains this specification under standard test conditions (TA = 25 °C).
Is the P6KE27C-E3/73 suitable for automotive applications?
Yes - the P6KE27C-E3/73 is RoHS-compliant and meets commercial-grade specifications; however, its HE3-suffix variant (P6KE27CHE3/73) is explicitly AEC-Q101 qualified for automotive use. The P6KE27C-E3/73 itself is rated for -55 °C to +175 °C junction temperature and validated for surge robustness per ISO 7637-2, making it appropriate for non-safety-critical automotive subsystems when qualified variants are unavailable.
How does the bi-directional design of the P6KE27C-E3/73 affect circuit layout?
The bi-directional design of the P6KE27C-E3/73 eliminates polarity marking and enables symmetrical placement across AC-coupled or differential signal paths. Unlike uni-directional TVS diodes, the P6KE27C-E3/73 requires no orientation check during assembly and supports identical protection on both sides of a balanced line - reducing layout complexity and eliminating risk of reverse installation in high-volume manufacturing.
What is the maximum clamping voltage of the P6KE27C-E3/73 under surge conditions?
The P6KE27C-E3/73 clamps to a maximum of 37.5 V when subjected to a 10/1000 μs waveform with 16.0 A peak pulse current (IPPM). This value is measured per industry-standard surge test methodology and represents the highest voltage the protected circuit will experience during worst-case transient events - directly enabling compatibility with 36 V-rated ICs and MOSFETs without additional voltage margining.
Does the P6KE27C-E3/73 have UL recognition for end-equipment certification?
Yes - the P6KE27C-E3/73 carries Underwriters Laboratories recognition under file number E136766, classified per UL 497B for protectors used in telecommunications and data line applications. This recognition permits direct inclusion in UL-listed end equipment without requiring additional system-level surge testing, accelerating time-to-market for certified industrial and telecom products using the P6KE27C-E3/73.
